摘要： Disclosed is a thermostatic valve, comprising an end cap (30), a valve body (10), and a valve core (40) located in a valve chamber (10a) of the valve body, wherein the thermostatic valve has a first outlet (101), a second outlet (104), a first inlet (103) communicating with the valve chamber, a first valve port (B) communicating with the valve chamber and the second outlet, and a second valve port (A) communicating with the valve chamber and the first outlet; and the valve chamber is further provided with a return spring (202) and a memory spring (201). When the temperature rises to a specified value, the memory spring produces an elastic force to drive the valve core to move overcoming the return force, shutting the first valve port. The valve body or valve core or end cap are provided with an initial position and an operating position, and at least one end of the memory spring is located at the initial position. When the temperature rises to a specified value, the memory spring deforms such that the rear end can disengage from the initial position and be kept in the operating position. The memory spring has a faster response time and can immediately switch to another flow path. The thermostatic valve is small in volume; and by means of providing the initial position and the operating position, a relevant device can be filled with a medium via the first outlet in an initial state.

摘要： A temperature regulating valve, comprising a valve body (1) in which a cavity (10) is provided, an end cover assembly, and a thermal actuator (2) and a first spring (31) that are mounted in the cavity (10). The valve body (1) is in communication with the outside by means of at least three ports; the thermal actuator (2) comprises an ejector rod (24) and a main body (22); one end of the thermal actuator (2) abuts against or is supported on the end of the first spring (31) proximate to the thermal actuator (2), and the other end of the thermal actuator (2) is limited to the end cover assembly. Moreover, the cavity (10) of the temperature regulating valve is further provided with a guide fitting part (21b) which comprises at least two protrusions (211), a recess (212) disposed between adjacent protrusions (211), and a ring-shaped part (210) of an approximate ring structure; the guide fitting part (21b) matches an inner wall of the cavity in a sliding manner, and/or the guide fitting part (21b) matches the thermal actuator (2) in a sliding manner. The temperature regulating valve has a simple structure, and the operation of the thermal actuator is more stable and reliable.

摘要： A thermostatic valve comprises a valve body (100) formed by die casting. The valve body (100) comprises: a valve main body (500) forming a valve cavity; a plurality of connection tube portions (101, 102, 103, 104); and installation base portions (201, 202) adjacent to the connection tube portions. Each of the connection tube portions comprises a straight tube section (10a) connected to the valve main body (500). A reinforcement member (40R) is provided between the straight tube section (10a) of the connection tube portion and the installation base portion adjacent to the connection tube portion. The valve body is formed by die casting, and respective parts of the valve body can be processed according to actual size requirements with no redundant material, thereby realizing a light weight of the thermostatic valve. Providing the reinforcement member satisfies a strength requirement when using die casting.

摘要： Disclosed are a temperature control valve (2) and a thermal management assembly (01) having the temperature control valve, the temperature control valve comprising a valve body (20), a first elastic element (22), a second elastic element (23), a valve seat component (24'), a valve core (25) and a thermal actuator (21). The temperature control valve comprises six interfaces and four valve mouths each forming a valve port: a first valve mouth (2022), a second valve mouth (243), a third valve mouth (240), a fourth valve mouth (2013). The temperature control valve comprises a first chamber (2010) and a second chamber (2020) not in communication with each other, one of the third interface (65), the fourth interface (66) and the sixth interface (68) of the six interfaces is in communication with the second chamber, and the other two interfaces thereof can each communicate with the second chamber via a valve port. One of the first interface (63), the second interface (64) and the fifth interface (67) of the six interfaces is in communication with the first chamber, and the other two interfaces thereof can each communicate with the first chamber via a valve port.
